Global Temperatures Could Rise More Than Expected, New Study Shows
December 20, 2009
The kinds of increases in atmospheric carbon dioxide (CO2) taking place today could have a significantly larger effect on global temperatures than previously thought, according to a new study led by Yale University geologists. The team demonstrated that only a relatively small rise in atmospheric CO2 was associated with a period of substantial warming in the mid- and early-Pliocene era, between 3 to 5 million years ago.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
